## Introduction

Greetings, Challenger! Welcome to our comprehensive guide on how to calculate percentage. In this article, we will provide you with all the necessary information and steps required to calculate percentage accurately. Percentage is a commonly used mathematical concept in various fields, including finance, science, and business. Understanding how to calculate percentage is a basic skill that everyone should possess. So, let’s dive in!

### What is Percentage?

Percentage is a fraction or a ratio expressed as a fraction of 100. It represents the proportionate part of a whole number. For example, if you scored 80% in an exam, it means you got 80 points out of 100 possible points.

### Why Calculate Percentage?

Percentage is essential in various fields, including finance, science, and business. Knowing how to calculate percentage is essential when calculating profits, discounts, taxes, and other financial aspects. In science, percentage is used when determining the concentration of a solution or when analyzing data.

### How to Calculate Percentage

To calculate percentage, you need to follow a simple formula:

Percentage = (Part/Whole) x 100

The above formula represents the percentage calculation of the part to the whole. Here, part refers to the fraction or ratio; whole refers to the total value of the fraction or ratio.

### Types of Percentage Calculations

There are three types of percentage calculations that are commonly used:

Type of Percentage Formula
Percentage Increase Percentage increase = [(new value – old value) / old value] x 100
Percentage Decrease Percentage decrease = [(old value – new value) / old value] x 100
Percentage Change Percentage change = [(new value – old value) / old value] x 100

### Step-by-Step Guide to Calculate Percentage

To calculate percentage, follow these steps:

#### Step 1: Determine the Total Value

Determine the total value of the part and the whole. For example, if you are calculating the percentage of a discount on a product, the total value is the original price.

#### Step 2: Determine the Fraction or Ratio

Determine the fraction or ratio that represents the part of the total. For example, if you are calculating the percentage of a discount on a product, the fraction or ratio is the discounted price.

#### Step 3: Apply the Percentage Formula

Apply the percentage formula (Percentage = (Part/Whole) x 100) to calculate the percentage. For example, if the discounted price of a product is \$60, and the original price is \$100, the percentage of the discount is calculated as follows:

Percentage = (60/100) x 100 = 60%

#### Step 4: Interpret the Result

Interpret the result. In this example, the result indicates that the discount on the product is 60%.
